According to Morgan, Hales was dropped due to a breakdown fo trust between hales and the group.
Senior players had a meeting all agreed he should be dropped and relayed this back to Giles who made the final decision

Yes the Guardian again....they must have a direct source....said it was Morgan and Bayliss and senior players who vetoed Hales coming in. I said before Hales is short of friends in the England side and it seems that way.
I don't like the phrase breakdown of trust(KP!!) but this is the biggest year for England and the players will know distractions and bad publicity is the enemy.
Hales was lucky he was not in the dock with Stokes back from that night in Bristol if you believe in Karma maybe it has come around.
No excuses for the ECB from me thou, I agreed with others is smells of a cover up, they have previous.
